目的分析2013年1—6月份天津市和平区疾病预防控制中心(CDC)对食品与公共场所从业人员甲型病毒性肝炎(甲肝)IgM抗体检测工作情况,旨在帮助该实验室工作人员了解2013年上半年甲肝IgM抗体检测工作的实际情况,并对下半年的检测工作提出指导性建议。方法整群抽取2013年1—6月来该区CDC进行健康检查中的食品与公共场所从业人员血清样本共计14 573份,按照年龄、性别、职业将其进行分组,并用北京万泰生物药业股份有限公司提供的甲型肝炎病毒IgM抗体检测试剂盒进行酶联免疫吸附试验(ELISA)。结果体检者的主要人群是20~29岁的年轻人,而甲肝IgM抗体阳性报告出现在40~60岁的体检者中,共计7例,其中男性1例,女性6例,不同性别间甲肝IgM抗体阳性率差异无统计学意义(P>0.05);IgM抗体阳性者在食品行业中有4例,公共场所行业中有3例,经检验两职业间甲肝IgM抗体阳性率差异无统计学意义(P>0.05)。结论甲肝IgM抗体阳性者主要集中在40~60岁的中年群体,且感染率在性别及职业间无显著性差异,提示该实验室在甲肝的检测工作中应加强对该人群的关注度,进一步做好甲肝筛查工作。
Objective To analyze the detection of hepatitis A (IgA) antibody against hepatitis A in food and public places by the Heping District CDC in January-June 2013, aiming to help the laboratory staff to understand 2013 Hepatitis A IgM antibody detection work in the first half of the actual situation, and the second half of the testing work to make recommendations. Methods A total of 14 573 serum samples from foodstuffs and public places practitioners from CDC in the district from January to June 2013 were collected and grouped according to their age, sex and occupation. Co., Ltd. to provide hepatitis A virus IgM antibody detection kit for enzyme-linked immunosorbent assay (ELISA). Results The majority of the subjects were young people aged 20 to 29 years old. The positive IgM antibody of hepatitis A was detected in 40-60 years old, a total of 7 cases, including 1 males and 6 females, hepatitis A and IgM (P> 0.05). There were 4 cases of IgM antibody positive in the food industry and 3 cases in the public places. There was no significant difference in the positive rate of IgM antibodies between the two occupations (P> 0.05) P> 0.05). Conclusions The positive IgM antibodies of hepatitis A are mainly concentrated in the middle age group of 40-60 years old, and the infection rate is no significant difference between sex and occupation, suggesting that the laboratory should strengthen the attention of this population in the detection of hepatitis A, Further improve hepatitis A screening.
